The present invention is capable of embodiment in forms for use on the oil filling or oil receiving pipes of engines of various characters and may be embodied either in the form of attachments or original features or parts of the engine structures. Throughout the following detailed description of the invention I will disclose several typical embodiments used on the oil receiving pipes as found in the various types of automotive engines which forms may be considered as appliances or attachments, or as devices or parts provided on the engines as originally constructed. It is to be understood that the present invention is not to be construed as limited to the specific forms or applications about to be described, but that it is to be taken as including any features or modifications that may fall within the scope of the claims.

The embodiment of the invention illustrated in Figs. 1, 2, and 3 of the drawings includes, generally, a body l forming apart of or a continuation of the oil receiving pipe I l of an engine E, a cover l2 for the upper end of the body it], and a cutter l3 carried by the cover l2 and operable to open sealed containers.

The body 10 is a tubular member constituting a continuation of the upper end portion of the oil receiving pipe and breather pipe of the engine E. The lower end of the fitting or pipe I l communicates with the interior of the engine. In the particular engine structure illustrated in the drawings, the receiver or pipe I I has its lower end held in or received by an angular tubular boss I l projecting from the body of the engine. The pipe H is vertical, it being understood that the form of the invention being described is capable of use in connection with tilted or inclined receiver and breather pipes. The body l0 projects upwardly from the upper end of the pipe I l, and in accordance with the broader aspects of the invention, may be applied to or attached to the pipe portion of the receiver in any suitable manner. In the particular case illustrated, the body iii has a lower cylindrical portion l5 tightly fitting into the upper end of the pipe ii that may be rigidly attached. to the pipe if found necessary or desirable. The body l0 fiares outwardly and upwardly so that its major upper portion i6 is considerably larger in diameter than the portion l5 and pipe H. The upper edge of the body iii may lie in a plane substantially normal to the longitudinal axis of the body and may be slightly turned out- Wardly or rolled.

The cap or cover [2 normally extends across the open upper end of the body ID to prevent objects and foreign material from. entering the receiver. The cover l2 carries the cutter l3 and operates to clean or filter the air breathed by the receiver during operation of the engine. In the form of the invention being described, the cover [2 is hinged or pivoted to the upper end of the body It] so that it may be swung from the closed position illustrated in Fig. 1 to the open position illustrated in Fig. 2. The cover l2 includes a main body part or disc ll adapted to seat on. the upper edge of the body Hi. The cover disc I! is hingedly connected with the upper end portion of the body ill by a pivot pin or hinge pin [8 passing through openings in lapping or meshing parts of the disc and body. The disc ii is provided with a stop 19 at its hinge connection to limit the outward swinging of the cover and to hold the cover in the inclined position illustrated in Fig. 2. The stop 19 is adapted to cooperate with the exterior of the body ill upon the cover reaching the fully open inclined position to step further opening movement. A spring finger or clip 20 is provided on the disc IT at a point diametrically opposite the hinge connection to engage under the rolled upper end of the body to releasably hold the cover in its closed position. The disc IT is perforated, being pro-vided with a multiplicity of spaced openings 2|.

The cover l2 may include an air filtering or straining means. A cup 22 is attached to the under side of the disc l'l' and holds or carries a suitable air filtering material 23. such as steel Wool, or the like. A plurality of spaced openings or perforations 2t is provided in the bottom or under-side of the cap 22. A deflector plate 24 may be provided on the upper side of the cover [2 to laterally deflect the oil laden and smoke fumes from the engine and to prevent the entrance of Water or foreign material into the receiver. The plate 24 is attached to the disc I! by a rivet 25 and is spaced from the disc I! by a. spacer 26 on the rivet. The peripheral portion of the plate 24 is rolled or turned down to the disc H and is notched or perforated to admit and pass air.

The cutter i3 is attached to the under side of the cover I 2 to be housed within the body l9 when the cap is in its closed position and to be exposed and accessible for use when the cover i2 is in its opened position illustrated in Fig. 2 of the drawings. The cutter l3'is formed so that it is operable to cut a large clean opening in an end of a container pushed or forced on to it, and is positioned on the under side of the cover [2 so that the contents of the container may drain directly into the body iii. In the preferred construction, the cutter I2 is substantially U-shaped in transverse cross section having two spaced side parts 21 joined by a transversely curved connected part 23. The cutter i3 is comparatively long but is proportioned so that it is freely received by the enlarged upper portion 96 of the body when the cover i2 is in the down or closed position. The connecting part 28 of the cutter is connected adjacent one end to the under side of the cup 22. In the particular case illustrated, the cutter is at: tached to the cup 22 by spaced rivets 29. A

spacer 38 is provided to space the connecting portion 28 of the cutter from the under side of the cup in parallelism with the under side of the cup. In accordance with the invention, the cutter i3 is attached to the under side of the cup 22 adjacent the periphery of the cup and adjacent to and in diametric alignment with the hinge connection between the cover and the body IS. The cutter it extends diametrically across the under side of the cover 12 from its point of connection with the cover. The longitudinal edges 3i oi the side parts 27 are pitched or inclined and converged to a point 32 at the outer or free end of the cutter. If desired, either one or both sides of the point portion or the cutter may be beveled. The inclined edges 3i are fiat and substantially normal to the side surfacesof the parts 21. Spaced drain. openings 33 may be provided in the cutter i3 at points adjacent the inner end of the spacer 30.

Means may be provided for releasably holding the cover l2 in the open inclined position illustrated in Fig. 2 of the drawings. In practice, any suitable type of device may be employed to releasably hold the cover in the open position. In the case illustrated in the drawings a releasable holding device 34 in the form of a flexible member is attached to the cover |2 adjacent its hinged connection with the body Ill. The releasable holding device 34 is bent or curved to have its free end pass through an opening in the wall of the body it when the cutter I2 is moved to its open position. A bend or notch 36 is provided in the device 34 to receive an edge portion of the opening 35 and the flexible device 34 is formed so as to spring or yield as its end enters the opening 35 to dependably hold the notch 35 in cooperation with the wall of the opening 35. Upon the cover l2 being shifted to its fully open position, the end of the releasable holding device 34 enters the opening35 and its notch 36 receives the edge portion of the opening to retain the cover in the open position. The device 34 may be released by bending it upwardly to disengage it from the wall of the opening 35.

It is believed that the utility and practicability of the form of the invention illustrated in Figs. 1 to 3 inclusive of the drawings will be readily apparent from the foregoing detailed description. The cover I2 is normally in its down or closed position illustrated in Fig. 1 where the cutter I3 is fully housed within the enlarged portion N3 of the body Ill. During operation of the engine E, air is free to pass in and out through the perforations in the disc l1 and cup 22 and is filtered by the material 23. When it is desired to open a sealed container of oil and drain its contents into the receiver of the engine, the cover M is opened and swung to the fully open position where it is inclined as illustrated in Fig. 2 of the drawings. The stop |9 and the releasable holding device 34 operate to hold the cover in this position. The container may then be pushed or forced down on the cutter l3 so that the point 32 of the cutter pierces an end of the container immediately adjacent its peripheral edge. As the container is pusheddown on the cutter l3 the space between the under side of the cup 22 and the part 28 of the cutter receives the adjacent wall of the container. In practice, the spacing of the cutter l3 from the. under side of the cup 22 is such that the bead commonly provided on the peripheral edges of sealed containers is slidable between the opposing surfaces of the cutter and cup. In this manher the under side of the cup 22 acts as a guide to guide the container as it is pushed downward on the cutter l3. In practice, the point 32 of the cutter may be spaced inwardly from the periphery of the cup 22 so that the bead at the edge of the container'may be brought against the under side of the cup to be uided thereby as the container is advanced on to the cutter. The pointed end of the cutter pierces the end of the container adjacent its periphery and the outer longitudinal corners of the'edges 3| cut or shear the end wall of the container as it is pushed down on the cutter thus enlarging the cut inwardly. The flat edges 3| engage the flap outlined by the cut and roll it upwardly and outwardly, leaving the opening substantially unobstructed. The spacer 3Q limits the downward movement of the container on the cutter i3 and aids in supporting the container. When the out has been made, the container is supported in an inclined position on the cutter l3 with the opening formed by the cutter in its lowermost portion directly over the open-mouthed body In so that the contents of the container are free to drain into the body Ill and pipe H. The cup 22 and spacer 30 space the cutter l3 inwardly so that the opened lower portion of the container is inwardly of the side wall of the body H] to prevent the oil from splashing or falling outside of the body. The openings 33 in the cutter |3 allow the oil from the outside of the cutter to freely drain out through the opening formed in the end of the container. The container is supported on the cover and cutter so that the user does not have to hold it or steady it as it drains. After the contents have drained from the container, the container may be readily pulled upwardly and disengaged from the cutter. The releasable holding device 34 may then be released to allow the cover l2 to be returned to its closed position. The sealed containers of oil may be easily and quickly opened by the device and their contents directly drained into the receiver of the engine. The containers are dependably supported in an inclined position on the cutter to insure the draining of all of their contents into the receiver. The provision of the cutter l3 on the under side of the cover l2 does not in any way complicate the structure or interfere with the breathing function of the receiver. When the cover I2 is in its opened position, the cutter |3 does not in any way interfere with the pouring of lubricant into the open end of the receiver.

The embodiment of the invention illustrated in Figs. 4, 5, and 6 of the drawings includes, generally, a body forming a part of or adapted to he applied to the lubricant receiver of an engine, a cap or cover 4| for the upper end of the body and a cutter 42 in the body 40 operable to a position where it is adapted to open sealed containers after shifting of the cover 4| to an open position.

The body 43 is adapted to constitute an extension or continuation of the upper end of the receiver I l The invention contemplates either the rigid attachment of the body 40 to the receiver H or the applying of the body 40 to the receiver in any suitable manner. In the particular case illustrated in the drawings, the body 40 includes a flared or substantially inverted frustroconical major portion 43 and a cylindrical lower portion 44 fitted into the upper end portion of the receiver H. The upper edge of the body 46 may be horizontal or in a plane normal to the longitudinal axis of the body and may be rolled as illustrated.

The cap or cover 4| is pivotally attached to the body 40 so that it may be shifted between a closed position over the upper end of the body and an open position out of vertical alignment with the upper end of the body. The cover 4| includes a substantially disc shaped member 45 proportioned to project beyond the upper edge of the body 40 when the cover is in the closed position. The peripheral edge portions of the member 45 are curved downwardly and a perforated disc shaped plate 45 is arranged at the lower peripheral edge of the disc 45 and is suitably attached to the disc. The plate 45 is spaced below the main part of the disc 45 to provide a space for holding an air screening or filtering'material 47. The peripheral portion of the plate 46 projects beyond the upper end of the body 40 and is perforated to allow for the breathing of air through the filtering material 4! in the cover. A pivot pin 48 extends through an opening in the plate 46 and a block 49 on the upper edge portion of the body 40 to pivotally attach the cover to the body. A spring 50 may be provided to normally yieldingly hold the cover in proper engagement with the upper edge of the body.

The cutter 42 for opening the containers of oil is mounted on the inner side of the main body portion 43 in a manner so as to be shiftable or operable between a position entirely within the body 40 and a position where it projects 'from the upper end of the body. In the embodiment of the invention being described, the cutter 42 is pivotally attached to the body 4|) so that it may be swung between the inoperative position in the body and the operative position where it projects from the upper edge of the body. The cutter 42 is substantially U-shaped in transverse cross section having spaced side parts 5| and a transversely curved connecting part 52. The longitudinal edges 53 of the side parts 5| are inclined and join at a point 54 at an end of the cutter. The edges 53 are preferably fiat and substantially normal to the side surfaces of the parts 5|. Spaced drain openings 55 are provided in the cutter 42 adjacent its broad end.

A guide 56 is provided in conjunction with the cutter 42 to guide containers on the cutter. The guide 56 is an elongate member spaced from and substantially parallel to the outer side of the cutter part 52. The guide 56 may be slightly curved in transverse cross section to effectively guide cylindrical containers. A spacer 51 connects the broad or lower end of the cutter 42 with the guide 55. The cutter and guide may be welded to the spacer 51. The inner or lower end of the guide 56 is pivotally connected with the body 40. A pivot pin 58 extends through openingsin the guide 56 and a connecting member 59 on the inner wall of the body 40 to pivotally connect the cutter and guide with the body. The cutter and guide are pivotally mounted on the inner flaring wall of the body 40 at a point spaced below the upper edge of the body and at a point substantially diametrically opposite the pivotal connection between the cover 4| and the body. The cover 4| is normally in its closed position where it seats against the upper edge of the body 40 and operates to filter the air breathed by the engine.

When it is desired to pour the contents of a container of oil in the crank case of the engine, the cover 4| is swung to its open position and the assembly of the cutter 42 and guide 56 is pivoted upwardly to the projecting position illustrated in Fig. 5 of the drawings. When the cutter 42 is in its projecting operative position, the outer side of the guide 56 bears against the inner wall of the body 40 providing an effective support for the cutter in addition to its pivotal mounting. The bead B at the peripheral edge of the container C is brought into engagement with the inner surface of the guide 56 and the container is pushed or forced downwardly on the inclined cutter 42 so the point 54 of the cutter pierces the end of the container. The guide 56 insures the engagement of the point 54 with the end of the container immediately adjacent its peripheral bead B and downward movement of the container on the cutter causes the outer longitudinal corners of the edges 53 to cut or shear the container end, thus enlarging the opening inwardly. The force exerted on the container C when it is opened on the cutter 42 is directed downwardly and inwardly toward the center of the body 40 so that it has no tendency to tip the assembly of the cutter and guide. The spacer 51 limits the downward movement of the container C and aids in supporting the container on the cutter. The

engagement of the container with the guide and cutter and the engagement of the cutter with the walls of the opening it has formed in the container end effectively supports the container in the inclined position on the cutter. The contents of the container are free to drain directly into the open mouth of the body 49 and flow into the crank case of the engine. The drain openings 55 allow the oil behind the cutter to entirely drain out of the container. As the container is effectively supported on the cutter the user is not forced to hold the container as it drains. After the container is entirely drained, it may be easily disengaged from the cutter and guide. The assembly of the cutter and guide may then be pivoted to its down position within the body 40 and the cover 4| swung to its closed position over the upper end of the body.

The form of the invention illustrated in Figs. 7 and 8 of the drawings includes generally, a body 6|], a cap or cover 6| for the body, and a cutter 62 shiftable between a position within the body 60 and a position where it projects from the upper end of the body.

The body 60 is adapted to be attached to or to form a part of the lubricant receiver N of the engine and is a tubular member forming a continuation of the receiver. The body 50 includes a cylindrical lower portion 53 engaging or fitting into the receiver part and a major portion 64 that is laterally enlarged so as to be adapted to receive the lower portion of a tilted container. The walls of the laterally enlarged portion 64 of the body are inclined upwardly and outwardly. The upper end of the body 60 may be straight and horizontal and may be rolled.

The cover 6| is pivotally attached to the body 50 so as to be operable between a position where it extends across the upper end of the body and a position where it is out of alignment with the body opening. The cover 6| may be similar to the cover 4| described above, that is, it may be a hollow substantially disc-shaped structure filled with steel wool, or the like, 65. The lower wall of the cover 6| is perforated and overhangs the upper edge of the body 60 to allow for the breathing of the engine through the receiver. A pivot .pin 66 pivotally attaches the cover 6| with the upper edge portion of the body 60.

The cutter 62 is longitudinally shiftable or movable between a position entirely within the body and a position where it projects from the upper end of the body. The cutter 62 is similar to the cutter 42 described above, being substantially U-shaped in transverse cross section. The

cutter 62 has two spaced side parts 61 and a transversely curved connectimg part 68. The longitudinal edges 69 of the side parts 51 are inclined upwardly and outwardly and converge to join at a point 19 on the upper end of the cutter. The edges 69 are preferably fiat and substantially normal to the side faces of the parts 51. Spaced drain openings may be provided in the broad end portion of the cutter. A guide i2 is provided in connection with the cutter 82 for carrying the cutter and for guiding the containers on to the cutter. The guide 12 is spaced from and substantially parallel with the curved outer portion 58 of the cutter and is connected with the cutter by a spacer 13. The spacer 13 may be welded to the lower end portion of the guide 12 and the lower end portion of the cutter part 68. The guide 12 extends upwardly beyond the pointed upper end of the cutter. In accordance with the invention, the guide 72 has sliding bearing engagement with the upwardly and outwardly inclined wall of the enlarged body portion' 64 and constitutes a carrier for the cutter, carrying or supporting the cutter for movement between its position in the body and its position projecting from the body. A slidable connection is provided between the assembly of the cutter and guide and the body 56. A longitudinal slot 74 is provided in the guide 12 and slidably receives a pin or rivet 15 projecting inwardly from the inclined wall of the body 60. The inner head of the rivet 15 engages the inner side of the guide 12 to retain the guide in proper sliding bearing engagement with the inner wall of the body 60. It will be apparent how the assembly of the cutter 62 and guide 12 are shiftable orslidable on the inclined wall of the body between the position illustrated in Fig. 7 of the drawings and the projecting operative position illustrated in Fig. 8 of the drawings.

Means is provided for releasably supporting or holding the assembly of the cutter 62 and guide 12 in its projecting operative position. A latch or stop 76 is carried by a spring arm 11 and is adapted to be engaged by the lower end of the guide 72. The stop 18 is adapted to project through an opening 18 in the inclined wall of the .body 60, and when in this position, is engageabl-e by the lower end of the guide 12 to support the assembly of the guide and cutter 62 in its up or projecting position. The spring arm Tl normally yieldingly urges the stop 75 inwardly so that when the cutter 62 is shifted to the up or projecting position, the stop 16 is automatically moved inwardly tobe engaged by the lower end of the guide 72. A suitable handle 19 may be provided on the spring arm l1 so that the stop 15 may be easily moved outwardly when it is desired to shift the cutter 62 down to its position within the body. In the construction illustrated in the drawings, the rivet 75 operates to attach the spring arm 71 to the body.

V The cover 6! is normally in its closed position over. the upper end of the body 60, and the cutter 62 and guide '12 are normally disposed within the body. When oil from a sealed container is to be poured into the crank case of the engine the cover 6! is swung to its open position and the assembly of the cutter 62 and guide 72 are shifted or slid upwardly on the inclined Wall of the enlarged body portion 6 3 to the up position illustrated in Fig. 8 of the drawings. When the guide and cutter reach this position, the stop 16 automatically moves inwardly under the guide to support the guide and cutter in the projecting operative position. The peripheral bead of one end of the container is positioned against the projecting upper end part of the guide 12 and the container is forced downwardly on the cutter 62. The point 78 on the upper end of the cutter pierces the end of the container immediately adjacent its periphery and the longitudinal outer corners of the edges 69 shear or cut the end of the container as the container is forced down on the cutter providing a large substantially unobstructed opening in the end of the container. The flat edges. 89 roll back the flap outlined by the cut so that it does not interfere with the draining of the contents from the container. The container is supported in a tilted orinclined position on the cutter after the out has been made so that its entire contents are free to drain out into the body 60 and receiver li As the lower end of the tilted container is disposed within the flaring or enlarged portion 64 of the body,

the entire contents of the container are received by the body and are prevented from splashing or over-flowing from the upper end of the body. After the oil has drained from the opened container, the container may be easily disengaged from the cutter and guide, and the stop 16 may be pulled outwardly so that the guide and cutter may be slid down to the inoperative position within the body. The cover 6! may then be swung to its closed position. The cutter 62 is always available for use and may be easily and quickly shifted to its operative position after the cover 6| has been swung to the open position. The cutter and guide do not interfere with the pouring of oil into the receiver and are normally entirely concealed and protected by the cover (H.

The embodiment of the invention illustrated in Fig. 9 of the drawings includes a body 80 forming a part of or adapted to be applied to the oil receiver H of an engine and adapted to receive the end portion of a container of oil, a cover 8! for the body 80, and a cutter 82 mounted Within the body 80 for opening a container pushed into the body.

The body 88 may be provided on or applied to the main part of the receiver H in any suitable or practical manner. In the particular case illustrated in the drawings, the body 89 includesa tubular lower portion 83 of circular cross section received in the upperend portion of the receiver part H. The body 80 has an enlarged upper portion 84 proportioned and shaped to receive a part of a tilted or inclined container. The enlarged portion 84 of the body is preferably partially cylindrical in transverse cross section to receive cylindrical containers, and its axis is inclined relative to the longitudinal axis of the receiver N The upper end of the body 80 may be straight and substantially horizontal. The cap or cover 8! may be similar to the covers 4| and SI described above. In the case illustrated in the drawings, the cover 8! is pivotally attached to the body 80 as at 85 so that it may be swung between the closed position and the open position.

In accordance with the embodiment of the invention illustrated in Fig. 9 of the drawings, the cutter 82 is mounted on or attached to the interior of the body 86. The cutter 82 is mounted on the interior wall of the enlarged body portion 84 so as to open a container that is forced or pushed on it. The cutter 82 is similar to the cutters 42 and 62 described above, being substantially U- shaped in transverse cross section to have spaced side parts 86 and a transversely curved connecting part 81. The longitudinal edges 88 of the side parts 66 are inclined and converge tola point 89 at the upper end of the cutter. Spaced drain openings 90 may be provided in the broad end portion of the cutter. The cutter 82 is attached to or mounted on the inner lower wall of the enlarged body portion 84. In the construction illustrated, the lower end part of the cutter 82 is attached to a spacer 9| on the inner wall of the enlarged body part 84. The cutter 82 is preferably attached to the lowermost portion of the interior wall of the body part 84. The spacer 9! supports the cutter 82 in a position where its portion 8? is spaced from and parallel to the inclined wall of the body portion 84.

In the operation of the form of the invention illustrated in Fig. 9 of the drawings, the cover 8| is swung to the open position when it is desired to open a container and drain its contents into the engine. The container held in a tilted position, is slid downwardly on the inclined wall of the body portion 94 so that the point 89 of the cutter pierces its lower end immediately adjacent its periphery. The wall of the enlarged body portion 89 forms an effective guide for the container as it is forced on to the cutter. The outer longitudinal corners of the edges 88 operate to enlarge the cut inwardly in the end of the container and 'bear against the flap outlined by the cut causing it to be rolled inwardly. The contents of the container are free to entirely drain out through the opening formed by the cutter and drain directly into the receiver. After the contents have drained from the container, the container may be easily disengaged from the cutter 82 and removed from the body whereupon the cover 9I may be swung to its closed position.

The form of the invention disclosed in Figs. 10 and 11 of the drawings includes generally, a body 95 on or forming a part of the lubricant receiver II of an internal combustion engine, a strainer cap or filtering cap 99 for the body and a cutter 91 removably seated within the body 95 adapted to be removed from the body and reseated therein in an operative position where it projects from the body to open a container pushed down upon it.

The body 95 may be suitably attached to the receiver II or may constitute a part of the receiver as initially constructed. In the particular form of the invention being described, the body 95 has a reduced lower portion 98 fitting within the upper end part of the receiver II and attached thereto by rivets 99. The tubular body 95 has a flared portion I99 extending outwardly from the portion 98 and an outer cylindrical portion II. In the particular case illustrated, the

' receiver is inclined and the longitudinal axis of the body is correspondingly inclined. The upper end of the body 95 may be straight and in a plane normal to the longitudinal axis of the body.

The cap 99 is removably arranged on the outer end part of the body 95 to filter the air breathed by the engine. The cap 96 includes a tubular shell I92 slidably fitting on the body part I9I and a disc I93 closing the outer end of the shell. A row of perforations or openings I99 is provided in the shell and screening I95 extends across the opening in the shell below the row of perforations I94. The screening I95 may have a flange fitting over the row of openings I94. The disc I93 has an inturned peripheral flange I99 overhanging the row of openings I94. It will be apparent how the screening 195 effectively filters or screens the air and how the flange I99 prevents the entrance of foreign matter into the openings I99. The cap 96 is easily removed from the body.

The cutter 91 is normally mounted within the body 95 in an inverted position and is removable from the body so that it may be righted or turned to an upright position and re-seated in the body so that it projects upwardly from the body to be operable to open a container forced down upon it. The cutter 91 is substantially U-shaped in transverse cross section having two spaced side parts I99 and a transversely curved connecting part I I9. The longitudinal edges II I of the side parts I99 converge to a point M2 on the upper end of the upright or righted cutter. Feet or mounting flanges II3 are provided on the lower ends of the side parts I 99. Drain openings II l extend upwardly from the lower ends of the side parts I99 and are separated by a tongue H forming a continuation of the curved connection part H9. The edges III are preferably flat and normal to the side surfaces of the parts I 99 to effectively shear the end of the container during the cutting operation. 7 V The cutter 91 is carried by a carrier II5 removably seated in the body 95. The carrier I I5 includes a ring IIB adapted to slidably fit in the outer portion I9I of the body and a web II'I extending across the opening of the ring. When the carrier H5 is positioned in the body, one of its ends is adapted to engage or seat on the shoulder II8 formed by the internal wall of the frustro-conical body portion I99. The web III is provided to support the cutter 91 and is perforated, having comparatively large spaced openings I29. The flanges II3 are seated on the web III and are suitably attached to the web. In the case illustrated in the drawings, the flanges III are welded to the Web. In accordance with the invention the legs I I3 are angularly related to the body of the cutter 91 to support the cutter on the web I I! so that it is inclined upwardly and outwardly when in its operative position. The cutter 91 is preferably substantially centrally disposed on the web I I1. One or more of the openings I29 in the web are in direct register or communication with the draining openings the cutter. A guide I2I is provided on the Web In to guide the containers on to the cutter 91. The guide is provided at its lower end with a laterally projecting mounting flange I22 attached to the web III. The body of the guide I2I is spaced from and is substantially parallel with the connecting part I III of the cutter. The guide I2I preferably projects beyond the point II2 of the cutter.

The carrier H5 is normally positioned in the body 95 so that the cutter 91 is on its underside and projects downwardly through the body. The cap 96 is normally mounted on the body 95 to prevent the entrance of foreign material to the receiver. When it is desired to open a container of oil and drain its contents into the lubricant receiver of the engine, the cap 96 is removed from the body 95 and the carrier H5 is taken out of the body. The carrier I I5 is disposed in the upper part of the body and is always easily engageable for removal. After the carrier II5 has been removed from the body it is inverted to right the cutter 91 to an upright position and is then returned to the body 95 to support the cutter 91 in the upstanding position illustrated in Fig. 11 of the drawings. The container may then be forced or pushed downwardly on the cutter to be opened thereby so that its contents may drain into the receiver. The point I I2 of the cutter operates to pierce the end of the container immediately adjacent its periphery and the edges III enlarge the opening, as the container moves downwardly, and rolls back the flap outlined by the out leaving a substantially unobstructed opening in the end of the container. The guide I2I effectively guides the container as it is being opened. The cutter 91 and guide IZI, in being inclined support the opened container in an inclined or tipped position with the opening in its lower end at the lowest point so that the entire contents quickly drain from the container. The openings I29 in the web allow the oil to freely drain into the receiver. After the contents have drained from. the container the container may be disengaged from the cutter and guide, whereupon the carrier II5 may be removed from the body and turned over so that the cutter is in an inverted position. The carrier H5 is returned to the body and seated in its original position and the cap 96 is placed on the upper end of the 40 connects the cover II to the body so that it may body. The container opening cutter 91 is removably seated 01' positioned in the body 95 in a manner so that it is convenient and accessible for use when it is desired to open a container of oil.- The cutter in being positioned directly over the opening of the body forms an opening in the end of the container which allows the entire contents to drain out without loss or leakage.

The embodiment of my invention illustrated in Figs. 12, 13, and 14 of the drawings includes, generally, a body I50 on or forming a part of the oil receiver II? of an internal combustion engine, a cap or cover I5I for the body, and a cutter I52 mounted in the body I50 for longitudinal movement between a position entirely within the body and an operative position where it projects from the upper end of the body.

The body I50 which forms an extension or continuation of the lubricant receiver II of the engine may be mounted on or attached to the receiver in any suitable or desirable manner. The particular body I50, illustrated in the drawings, is an elongate tubular member having a reduced lower portion I53 fitting into the upper end portion of the receiver part I I The body I50 flares upwardly and outwardly from the upper end of the part I53 and has a. main enlarged upper portion I54 with cylindrical internal and external walls.

The cover I5I may be in the nature of any suitable air filtering means for the upper end of the body I50. In the particular application of the invention being described, the cover I5I is similar-to the covers 4! and 6I described above, being a substantial disc shaped hollow member filled with steel wool, or the like. The lower wall of the cap or cover I5! is provided with a plurality of openings I56 and over-hangs the upper end of the body to allow for the passage of air into and out of the receiver. A pivot pin I51 pivotally be swung between the open and closed positions.

The cutter I52 is supported in the enlarged upper portion I54 of the body for longitudinal movement between a position where it is entirely within the body and an operative position where it projects from the upper end of the body. The cutter I 52 is similar to the cutter 91 described above, being substantially U-shaped in cross section;' The two side parts I58 of the cutter are parallel and in substantial vertical planes, while the curved connecting part I59 of the cutter is inclined upwardly and outwardly. The longitudinal edges of the side parts I58 are inclined upwardly and outwardly and converge to a point I6I at the upper end of the cutter. Drain openings I62 are provided in the lower end portions of the side parts I58 and are separated by a tongue I63 which is a continuation of the connecting portion I59. The lower end of the tongue I63 may be curved or bent inwardly as illustrated in the drawings. Inwardly projecting feet or flanges I64 are provided on the lower ends of the side parts I58 of the cutter.

The cutter I52 is supported by a vertically or longitudinally shiftable carrier comprising a ring I65 and a web I66 in the ring. The ring I65 is shiftable or slidable longitudinally in the enlarged upperportion I54 of the body between the position illustrated in Fig. 12 and the position illustrated in Fig. 13. The web I66 is attached to the ring I65 and is substantially discshaped to fit the opening in the ring. In accordance with the invention, the web I66 is provided with a plurality of spaced openings I61. The

flanges I64 on the lower end of the cutter I52 are seated on the upper side of the web I66 and are attached to the web in any suitable manner. In the particular case illustrated, the flanges I64 are attached to the web by welding. The flanges I64 are preferably attached to the upper side of the web I66 at or adjacent its center. The flanges I64 are related to the body parts of the cutter I52 so that the cutter projects upwardly and outward- 1y from the surface of the web I66. A guide I66 is provided for guiding the containers on the cutter I52. The guide I68 may be curved in transverse cross section and is mounted on the upper side of the web I66 so as to be spaced from and substantially parallel to the outer surface of the cutter part I59. The guide I68 projects upwardly beyond the upper end of the cutter I52 and is provided at its upper end with an outwardly projecting extension or tongue I10. The tongue I10 is adapted to engage the upper end of the body I56 to support the cutter and carrier when they are in the down position entirely within the body. A notch I1I may be provided in the upper edge of the body I50 to receive the tongue I10.

Means is provided for guiding the cutter carrier for longitudinal movement in the body I50 and for supporting the carrier when the cutter is in the operative position. A plurality of circumferentially spaced longitudinal keys I12 is provided on the interior walls of the enlarged body portion I54 for cooperating with key-ways I13 in the carrier ring I65. The keys I12 terminate at points spaced below the upper end of the body I 50 and the cutter carrier is shiftable upwardly so that its key ways I13 may be disengaged from the keys whereupon the carrier may be turned so that the lower end of the ring I65 is supported on the upper ends of the keys I12 so that the cutter I52 projects from the upper end of the body. I

It is believed that the operation of the embodiment of the invention illustrated in Figs. 12', 13, and 14 of the drawings will be understood from the foregoing detailed description. The cutter I52 is normally entirely within the body where the tongue I16 supports the'as'sembly of the cutter guide and cutter carrier in the body. When it is desired to open a sealed container of lubricating oil and drain its contents into the crank case of the engine, the cover I5I is swung to the open position so that the projecting tongue I10 which may serve as a handle may be engaged for shifting the assembly of the cutter, guide, and cutter carrier upwardly in the body. When the ring I65 of the cutter carrier reaches the upper end portion of the body where its key ways I13 are disengaged from the keys I12, it may be turned so that its lower end may engage the upper ends of the keys to support the carrier and cutter 1n the up position. The cutter I52 and the guide I66 then project from the upper end of the body I50 so that a container may be pushed downwardly on the cutter to be opened. In opening the container, the bead at its lower end is arranged against the inner surface of the projecting portion of the guide I68 and the container is pushed downwardly so that the point I 6I of the cutter pierces its lower and immediately adjacent its periphery. The outer longitudinal corners of the edges I60 operate to out or shear the end wall of the container as the downward movement of the container continues, thus enlarging the opening. The edges I 60 are preferably flat so that they engage the flap outlined by the cut to roll it back out of the opening formed.

by the cutter. As the guide I68 and the outer portion I59 of the cutter are inclined, the container when opened. and supported on the cutter and guide is also inclined and has the opening formed by the cutter in its lowermost part. The oil is free to drain from the opening made by the cutter and discharges through the openings it? directly into the lubricant receiver of the engine. As the container is tipped or inclined when opened and supported on the cutter, its entire contents are free to quickly drain into the receiver. The drain openings I62 in the cutter allow the free drainage of oil from behind the cutter. After the contents have completely drained from the container the container may be removed. or disengaged from the cutter and guide so that the assembly of the cutter guide and cutter carrier may be returned to its normal position in the body. To return the assembly to its down or normal position, the assembly is turned so that the tongue H0 is in vertical alignment with the notch IH in which position the key ways H3 register with the keys I12 and receive the keys allowing the assembly to be moved downwardly in the body. The tongue H0 is received by the notch I'll in the upper end of the body and is effectively retained in the notch by the cover I5 I. The container opening cutter I52 of the device is normally concealed and protected within the oil receiver of the engine but is at all times accessible for use. The cutter may be quickly shifted to its up or operative position and the containers may be quickly opened by the cutter so that their contents may completely drain directly into the lubricant receiver of the engine.
